4. CALIBRATION

The person or institute who not only does not have the acknowledge but also is not  

The calibration is required periodically.  * precision use : one time after 180 days.

 

  * nomal use : 1 time/one year. 

There are some relative error caused by decrepit power supply, circumstance temperature, 

humidity and various environment. Therefore, if you calibrate bespoke to mentioned circumstance, 

you can use the power supply under optimum.

4-1. Characteristics

No need to open the power supply cover. 

Be able to calibrate by using front panel key.

Be able to calibrate by using remote interface.

Store in non-volatile memory permanently.

Be able to restore and backup the calibration data. 

Easy to calibrate by comparing between calibration equipment and power supply

 at a one   to one method.

4-2. Preparation for Calibration.

Use more higer precise measuring instrument than the power supply. 

Warming up the power supply and measuring instruments while 1 hour or more at room

  temperature 20℃ ~ 30℃. 

Calibration humidity must be below 80%.

Connect between the power supply's output bus bar and measuring instrument there are no  

 contact resistance. 

Connect the power supply's GND and measuring instrument's earth terminal with AC input

   power's GND. 

Block and turn off the magnetic generating and not related calibration devices from the 

power supply and measuring instruments.

 Warning

 -  54 - 

 certificate calibration center  should not calibrate the power supply.
